Definitions

  • the present invention relates generally to a multilayer interlayer and a glass laminate containing such interlayer. More particularly, the present invention relates to a multilayer interlayer containing at least one ionomer skin layer and at least one sound insulating intermediate layer, in which a glass laminate containing such interlayer possesses a desirable combination of acoustic damping, acoustic barrier, flexural strength, bending stiffness and optical properties, and optionally solar heat shielding properties, which can allow for reducing the weight of the resulting glass laminate.
  • the multilayer interlayers according to the present invention it is possible to prepare a laminated glass with excellent sound insulating characteristics, flexural strength and stiffness. According to this, it becomes possible to apply the laminated glass in a place where good external load influence and sound insulating properties are required, such as glass building materials for building and sunroofs or rear glasses for automobiles. Meanwhile, in view of the fact that the laminated glass is excellent in flexural strength and stiffness, it also becomes possible to thin the glass to be used for the laminated glass, and weight reduction of the laminated glass can be realized while still maintaining acceptable strength and stiffness of the laminated glass.
